IMPROVEMENT IN REVERSlBLE PLOWS.

Specification forming part of Letters Patent No. 180,7] 3, dated August8, 1876; application filed December 1, 1875.

To all whom it may concern:

.Be it known that I, JULIUS HARTMANN, of the city of Louisville, in thecounty of J efferson and State of Kentucky, have invented a certain newand useful Improvement in Reversible Flows; and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the same,reference being had to the accompanying drawings, forming part of thisspecification, in which Figure l is a perspective view of the plow,showing its general construction. Fig. 2 is a view of the land-side ofthe standard-frame, showing the mechanism for operating the mold-board.

Similar letters of reference indicate corresponding parts of thedrawings.

This my invention relates to a new improvement in reversible plows, butmore especially to the peculiar construction of the mold-board, andgeneral arrangement of the mechanism by which it is operated the objectof which is to provide a plow that will be cheap, durable, and easilyoperated, and, at the same time, one that can be so changed, withoutmaterial loss of time, as to enable the operator to use it alternatelyback and forth on the same side of the land without passing around it,as becomes necessary where the stationary moldboard is used.

This invention will be more fully illustrated in detail in perspectiveviews, Figs. 1 and 2 of the drawing, in which Ais the plow-frame, all ofwhich is made similar to those now in common use. B is thestandard-frame, which is made of cast-iron or other metal, and in formas shown in the drawings. This frame B extends downwardly to a levelwith the base of the share, and is formed with a bed or plate, L, thatconstitutes the land-side'of the plow. O is the lever for operatii'igthe look-pin that holds the mold-board when set. D is the lockpin, whichis made to slide in a boss cast on the heel or land-side of thestandard-frame in such a manner as to enable the end to enter a hole inthe thick part of the share, to hold it firmly in position,butsusceptible of being changed to the other side and reset again at theend of each furrow, which is done by means of the lever G at the side ofthe beam for that purpose, which lever may be kept in its place, whenset, by a spring-catch on the beam. Eisthe revolving mold-board, whichis made of sheet metal, bent in the form of a half-circle, with the endsbeveled in such a manner as to give it the required backward slope tocause it to turn the furrow without dragging. F F are the share-points,all of which are made of steel or other metal, and attached to themold-board similar to those now in use, except that they are made' heavyat the heel, in order to receive the end of the locking-pin, by whichthey are held in position; Gis the colteror cutter in front, which ismade of steel, and secured between the points of the mold-board, asshown in the drawing. H is the spindle of the mold-board, which is madeto work in bearings in the standard-frame B, with the mold-board securedfirmly to the end by means of rivets through it and the flanges on theboss of the spindle, by which it is held in position, so as to be easilyturned to either side, to answer as a right or left handed plow, that issusceptible ofbeing locked in either position,or changed at the pleasureof the operator. A handle, I, is provided on the outer end of spindle H,for use in reversing the share, by which means this operation will begreatly facilitated.

Having thus fully described the nature and object of this my invention,therefore what I claim as new, and desire to secure by Letters Patent inthe reversible plow, is-

The standard or frame B, having the landside L formed therewith, incombination with the reversible share or mold-board E F G, thereversing-spindle, and the share-locking mechanism, substantially asshown and described. Witnesses: J ULlUS HARTMANN.
